STUFKFING-Box.

SPECIFICATION forming par-t of Letters Patent No. 658,207, dated, September 18, 1900.l

Application 'filed July 5, 1900. Serial No. 22,577. (No model.) v

To all whom it may concern/ Be it known thatpI, CHARLES CLARENCE- OONROY, a citizen of the Unite'd States, and a resident of Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Stuffing-Boxes; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of draw'- ings, forms a full, clear, and exact specification, which will enable'others skilled in the art to which it appertains to make and use the same.

This invention has general reference to improvements in stuffing-boxes; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described and then pointed out in the claims.

In the drawings already referred to, which serve to illustrate this invention more fully, Figure lis an elevation of this irnprovedstu ffing-box. Fig. 2 is a side elevation of the same, `and Fig. 3 a longitudinal vertical section in line A A of Fig. 2.

Like parts are designated by corresponding.

symbols of reference in Vall the figures.

The object of this invention is the production of a stuffing-box for rotating and reciprocatin g rods and shafts that shallbe capable of yielding, be adjustable, and to a certain degree self-adjusting to any Variation in the alinement of the stuffing-box body,`the pipe, and the rod or shaft moving in the same. To attain these objects, this stufng-bomwhich is primarily designed for oil-well pumps, but is also capable of being used for variousother purposes, consists of a body a, which in the present instance is composed of a standard pipe-fitting, designated a cross7 1, into the horizontal branches of which are screwed or otherwise secured nipples 2 and 3, while the lower vertical branch is screwed upon the pump-discharge pipe 4. Into the upper vertical brauch ofv this cross is fitted a hose-nip-A ple 5, to which is secured, by a band or otherl suitable hose-pipe fastenings 6, the lower end of a short section of a comparatively-heavy rubber or other elastic tubing?, the upper end of which is secured to a hose-nipple 8 by This nipple 8 is either formed ina band 9.

tegral with a stufng-box body lO orsuitably' jfastened thereto, said stuffing-box bodyhaving the usual laterally-projecting anges l1 stuffing-box gland is arranged to compress the rod-packing there are used in this present case two eyebolts 14 and 15, consisting of round rods having their lower ends formed into eyes 16 and 17 and their upper ends screw-threaded to receive lock-nuts 19 and 20 and adjusting-nuts 21 and 22. The eyes of these bolts 14 and 15 are passed overthe nipples 2 and 3 or, Where necessary, the bolts are first passed through the holes in the flanges of the stuingLboX body and then the nipples 2 and 3 passed through the eyes 14 and l5 and then screwed into the horizontal branches of the cross 1, after which the lock-nuts and adjusting-nuts are properly adjusted, thereby securely holding the stuffing-box body lO in position and preventing internal pressurek from dislodging the elastic tube sectionor the stuffing-box body 10, and at the same time enabling the followeror gland 23 being adjustedito compress the packing 13 vand make a tight joint for the rod 24.

It will now be observed that in cases wherev vthe center line of the pipe 4 and that `of the stuffing-box body a, do not coincide with the rod 24-as, for instance, when this stuffing- 'boX is used in an oil-Well pump-the stuingbox` body is capable of yielding in the direction to the right and left of Fig. 2, and majT be adjusted in two directions at right angles thereto by manipulating' the lock-nuts 19 and:

20 in the proper self-evident,directions.

I have heretofore stated ythat this self ad justing and adjustable stuffing-box. may be used for other purposes than pumps. Forinstance, this device may, with` but a slight Y,

modification, be successfully appliedr as a .stern-tube for the smaller types of steam vessels and pleasure crafts and boats,in.which case the pipe `4 will be securely fastened in the stern-post of a ships frame and the nipples 2 and 3 closed on their ends or solid plugs substituted therefor. The rod 24 would in this case be the propellershaft, and this would be tightly packed by the stufng-box',

IOO

In steam vessels it is frequently very difficult to keep the stern-bearing tight, owing: to the fact. that an unequal distribution of the load, passengers moving about, eine., disturbs the alinement of the propeller-shaft and the stern-post tube. overcome by the introduction of my iiexible and yielding tube-section 7 and the fact that thereby the stuffing-box body is Se] f-adj ustmg.

The body a, heretofore described as being com posed of commercial pipe-fittings, may be made in one piece of casting or forging without departing;r from the nature of this invention.

Having thus fully described this invention what is claimed as new, and desired to be se cured by Letters Patent of the United States, is

l. In a stufling-box, a base part, a yielding, flexible and elastic tube section secured thereto, a stuliing-box body secured to said tu be-section, and a gland for the stuing-box, as described.

2. In a stuing-box, a base part, a yielding,

This objection is entirely to. one of said branches, a stuiiug-box body secured to said tube-section, a gland for said stuffing-box, and tie-rods secured to the hori zontal branches of said base part and passing,r through the flanges of the stuffing-box body and its gland and provided with nuts, as stated.

4. In a stuiiing-box, a base part consisting of a commercial pipe-fitting cross, a hosepipe nipple in the upper Vertical branch of said cross, an elastic, flexible and yielding tube-section secured to said nipple by aband or other suitable fastening, a stuing-box body secured to the upper end of said tubesection, a gland for said stufiing-box, tierods having eyes as described, nipples passed Vthrough said eyes and secured in the `l1ori zontal branches of said cross, and nuts at the upper ends of said rods, whereby the gland may be adjusted and the stuffing-box body adjusted, as and for the object stated.

5. In a stuffing-box, a base portion, a flexible, yielding and elastic tube-section secured thereto, a smiling-box body secured to the upper end of said tube-section, and` suitable means for adjusting said stuiilng-box body upon said tube-section, as set forth.

In testimony that l claim` the foregoing as my invention I have hereunto set my hand in the presence of two subscribing witnesses.

CHARLES CLARENCE CONROY.
